InputField inside a CompositePart

Hello

Using builder to get an InputFieldSpec, for example:

myInput := InputFieldSpec model: aValue layout: (LayoutFrame
leftOffset: 5 topOffset: 180 rightOffset: 200 bottomOffset: 200 )

Also, i've a windows with a composite part, ie, if i run:

myWindow builder composite components at: 1

i get:

a SpecWrapper on: a BoundedWrapper on: a WidgetStateWrapper on: a CompositePart

I'd like to add myInput inside that compositePart, is possible to do that ?

regards
r.
